By means of this arrangement thebearing surfaces can be easily and readily renewed when worn.

The invention also consists in providing a ldisc'onnectible 'connection of the several frames in such a manner thatthe two slde members which are to be connected together are made to abut against each other and a projecting strap is fixed on one side member, 1n such a manner that it engages by means of a slot over a bolt fixed to the other side member and is held firmly by means of a thumb nut screwing on the said bolt.

frame a. This simple ball bearing for the rollers effects an extremel- ,`t," easy guldance of the rollers and allows of readily renewing the bearingnfter the balls have become worn.

l he frames `a whichare about from 1 to 2 meters long-are connected together in twos or more according to the length of the chute run, at the place of building, and are taken apart f r transport.

y For the purpose o parts together straps k are fixed by means of each over a bolt m vfixed to the other side member. On the bolt m is a ring'nut n provided onits undersidewith Aa 'shoulder or extension o engaging in a circular part of. the slot l, whereby the stra can be un one only after the nut has geen completely screwed back. This arrangement prevents av separation of the single parts of the frame' during the operation of .the device. The frames are connected together by passingA the bolts m of one frame into the slots Z of ing the nuts up, whereby the ends of the side` vent the formation of a kink or angle.

Having now particularly described and ascertained the nature of my saidinvention 'and in what manner the same is to be performed, I declare that what I claim is Ball bearing ofthe character described comprising in combination a carrier for said bearin provided with annular grooveshin-r vterme late lts ends, disks .endwlse inserted mtojsaid carrier provided with recesses m 1 their outer faces, a ball resting in therecess of each disk, set screws .passino laterally through said carrier eac'hprovid5 cavity at4 the inner end constituting ,with the recess of each disk -a bearing for said ball for pressing the disk in opposite directions against the outer walls of said grooves, substantially as described.
